Patent EP-0271280-A3 (EP)
IPC: G06F3/0488
Filed: 1987-12-03
Abstract: A personal computer (20) connected to a display and touch screen panel (15) is 
provided with a form entry system integrated therewith. The form entry 
system is adapated to display a predefined form (e.g. 30), and to automatically 
display a predefined tool, such as a keyboard, menu, calculator, etc., 
(40,50,60,70,80,100,110) to facilitate inputting information in a respective field of 
the form or chart. Specifically, the user is prompted as to which field is to be 
filled in by highlighting the field (e.g. 41), and concurrently displaying as an 
overlay (window) the tool (e.g. 40) that the user will use to input the 
information identified in the highlighted field. In the case where a field calls 
for, for example, the insertion of a name, the system may be adapted to display 
a menu of names as the tool for filling in that field. The user selects the name 
that he or she desires to be inserted in the field by touching that name. The 
system responsive thereto inserts the name in that field, highlights the next 
field to be filled in and displays the tool for filling in that field. They system 
may also be adapted to communicate with a host computer (140) to obtain the 
information that is to be inserted in one or more fields. Also, the user may 
erase the tool that is displayed by the system an direct the system to display 
another tool, such as the aforementioned keyboard.

Title: Power supply for producing a regulated voltage
IPC: H02M7/217
Filed: 1988-10-26
Abstract: A power supply is proposed for producing a regulated DC voltage from a mains AC voltage, which power supply has a mains transformer (10), a downstream rectifier arrangement (11) and a semiconductor element (13), connected in a DC voltage line leading away from the rectifier arrangement (11), which can be controlled as a function of a predeterminable nominal value (U2) and the actual value of the output DC voltage (Ua). The semiconductor element (13) is exclusively switched between the saturation and blocking state, a control device (16, 17, 19) which switches on the saturation state if the actual value is less than the nominal value and switches on the blocking state in synchronism with the mains AC voltage or the rectified voltage half-cycles derived therefrom, is allocated to the semiconductor element (13). The output DC voltage is applied to a capacitor (18) connected to the output of the power supply. Since the semiconductor element (13) is exclusively in the saturation or blocking state there is practically no power loss, or at least only an extremely small power loss, so that the power supply can be produced cost-effectively and with a small volume. <IMAGE>

Filed: 1988-01-12
Abstract: A narrow tape of polyester or other suitable plastic for use as a tear tape in the packaging industry slit from a wide web of the material, is coated wholly on one side and preferably at the edges with a suitable release material. Downstream of the slitting the tape is printed on the other side, then coated over the printing with a suitable pressure sensitive adhesive, said coating width being narrower than the width of the tape covering the printing and spaced from both side edges of the tape to avoid pick-off onto tape guide surfaces. The tape is then wound onto a core with both radial and axial traversing movements. The tape is then supplied to the packaging line preformed with adhesive to avoid on-line adhesive applications.

Title: Method for realizing a control procedure in combination with the possibility of directly addressing a subscriber in a calculator-controlled communication system, especially a key system
IPC: H04M3/50
Filed: 1989-07-31
Abstract: If a call connection exists for a second terminal (T2) (secretary station), which is associated with a first terminal (T1) (executive station) in a particular switching arrangement, a signalling information can be transferred from the secretary station to the controller (ZSt), which has the consequence that the line on which this call connection is effected is placed on hold and that, at the same time, a command for activating the direct-listening hands-free speaking facility (LFS1) belonging to the executive station is transmitted. Furthermore, a consultation connection is established between the secretary station and the executive station. When the secretary station (T2) goes on hook or when an action is taken, the effect of which corresponds to this going-on hook, the executive station (T1) is automatically connected to the line (L) which is on hold, maintaining the direct-listening hands-free speaking mode of operation. Thus, a call connection is switched to the executive station without the subscriber concerned having to undertake any action at his terminal. <IMAGE>
